Hands-on TCP/IP

Course Description

Hands-on TCP/IP explains the concepts, parts and pieces that, taken together, form the TCP/IP suite of protocols. For instance, the IP protocol performs the essential function of routing data packets to the right place. How does it do this? How does IP work with TCP to provide a reliable end-to-end connection? These are some of the questions we pose and answer in this class.

TCP/IP provides five core services. We discuss, define and relate all of them and show how they work with each other to provide a complete set of services.

A key feature of this class is that theory is translated into practice by building a TCP/IP-enabled Ethernet or token ring LAN, then examining what happens as TCP/IP traffic travels back and forth over the LAN. In these labs you will build LANs and configure TCP/IP on Windows workstations. You will see how a normal conversation flows as well as create and watch abnormal connections by using a LAN protocol analyzer.

One of the most important and useful skills in working with TCP/IP is the ability to subnet a TCP/IP network. We will explain what subnetting is, why a subnet mask is useful and needed and how masks are calculated to meet a variety of needs. You will learn shortcuts to simplify this task including a subnet mask calculator and a "cheat sheet" as well as simple ways to ensure that you have calculated the masks you desire correctly.

You will learn handy troubleshooting tools found in both workstations and routers. Commands such as PING, ARP, TRACEROUTE, ROUTE PRINT and NETSTAT will be introduced and discussed. You will use these commands (and their many options) to show that links are really up and working, and if not, why not. You will learn simple, effective troubleshooting methods that will help you quickly isolate and correct many TCP/IP malfunctions.
 

Objectives

When you complete this course, you will be able to:

· Explain the five core functions of TCP/IP
· Identify the specific protocols that provide these functions
· Discuss flow control mechanisms in TCP/IP; their strengths and shortcomings
· Configure and install a LAN running TCP/IP on Windows NT workstations
· Capture LAN traffic with a protocol analyzer and interpret the results
· Calculate subnet masks and subnet a TCP/IP network
· Learn how to use simple but effective TCP/IP troubleshooting methods
· Use built-in diagnostic tools (e.g., PING,  ARP, TRACERT, NETSTAT)
· Recognize TCP/IP failures quickly and take corrective action
· Use essential utility applications such as Telnet and FTP
· Implement network services including DNS, DHCP and SNMP
· Learn tips on how to get the most out of your TCP/IP network

Instructional Methods

Balanced lecture/discussion; self-quizzes, paper and hands-on exercises.
 

Audience

Network personnel responsible for the sale, design, installation and maintenance of TCP/IP networks. Typical students include systems engineers, network managers, architects, product specialists, performance analysts and support personnel. Systems managers, integrators, computer and communications specialists and applications personnel will find this class especially valuable.
 

Prerequisites

While self-contained, some familiarity with LANs and the OSI model is recommended.
